Rainbow six siege operator?

Hey I've been playing rainbow six siege for a long time now and I'm now trying to get all the trophies on the ps4, only there's a task that I have to play a round with each original operator, I still don't know whether they are all operators or certain ones

I suspect that this refers to the operators who appeared at the beginning of the game. As far as I know, they are GIGN, GSG 9, Spets Natz, FBI and SAS.

These are all operators that cost less than 10,000 reknown.

So for the attackers Sledge to Blitz, for the defenders Smoke to Bandit.
